NON-RECIPROCAL CIRCUIT ELEMENT AND MANUFACTURING METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a non-reciprocal circuit element which has satisfactory assembling performance of electronic components, is capable of performing properly accurate assembling, is inexpensive and has satisfactory productivity, and to provide a manufacturing method thereof. SOLUTION: This non-reciprocal circuit is provided with a resin case 9 fixed on a second yoke 3, constituting a magnetically closed circuit in cooperation with a first yoke 1 and a plurality of electronic components C1, C2, C3 positioned inside this resin case 9 and respectively connected to port portions 5a, 6a, 7a of center conductors 5, 6, 7. Since a plurality of recognition marks 9h for mounting the electronic components C1, C2, C3 are provided in the resin case 9, the electronic components C1, C2, C3 can be housed correctly in the resin case 9 using these recognition marks 9h as a reference. Accordingly, even if deformation, such as twisting or bending occurs on a hoop material 21, positional deviation between the electronic components C1, C2, C3 and the resin case 9 never occurs, and assembling can be performed with proper assembling performance and high accuracy.
